Question

the model below represents the potential genetic outcomes for offspring of two parents. each parent carries one allele for normal red blood cell production (n) and one allele for abnormal red blood cell production (n). a carrier is an individual who has only one allele associated with a disease and who does not usually show symptoms of the disease. which statement is generally true for an individual who inherits the mutated sickle cell anemia gene from only one parent? 1 the person will not be able to carry enough oxygen to body cells. 2 the person would be unaffected and able to produce enough healthy red blood cells to transport oxygen. 3 the person will produce clumped hemoglobin if the sickle cell gene was inherited only from the mother. 4 the person will be able to transport more oxygen than someone who does not inherit this gene from either parent. student answer

Explanation:

Sickle cell anemia is a genetic disorder. A carrier (inheriting one mutated gene) typically shows no symptoms (unaffected) and can produce enough healthy red blood cells to transport oxygen, as the normal allele helps. Option 1 is wrong (carriers can carry enough oxygen). Option 3: Clumped hemoglobin occurs in homozygous (two mutated genes) cases, not carriers. Option 4: Carriers don't transport more oxygen than non - carriers. So option 2 is correct.

Answer:

1. The person would be unaffected and able to produce enough healthy red blood cells to transport oxygen.
